Abstract
A method of making a golf club includes making a first determination of the location of the effective seam in a shaft and then more precisely locating the seam before attaching a golf club head with the face of the club head facing in a neutral direction.
Claims3
A method of determining the location of an effective seam in a golf shaft having a butt end and a tip comprising the steps of:
- a) determining as one approximation of the location of the effective seam one of four quadrants in which the effective seam lies by fixing the butt end of the shaft and deflecting the tip while observing the motion of the tip;
- b) noting the quadrant for which the motion of the deflected tip is oscillation substantially in a plane;
- c) applying a weight at approximately the midpoint of the shaft and
- d) measuring the deflection of the shaft at a plurality of points of the noted quadrant with the point displaying the highest deflection corresponding to an effective seam location on the circumference of the shaft.
